| Abstract | ||||
| The toxicity and biochemical response of E. vermiculata land snail to Niclosamide molluscicide were laboratory tested using spraying technique on most soil. Also, the efficiency of the molluscicide was tested under field conditions. Data revealed that the tested molluscicide at concentrations of 0.14,0.17, 0.2 and 0.29 ppm exhibited 20, 43.3, 66.7 and 93.3 % mortality of snails with LCso value of 0.631 ppm. Results of sub lethal concentration (Y4 LCso) effect showed that % activity of Peroxidase and Catalase enzymes after 0.0, 24h, 48h, 72h, and 96h were (100, 183.3, 49.63, 85.57 and 64.1) and (100, 137.5, 124.4, 150 and 103.1 %) respectively. The effect of % LCso on GOT, GPT, AchE, LDH, total protein and total lipids of the snail after 24, 48, 72 and 96 hours post-treatment were (-3.8, -61.9, -41.9 and - 33.3 %), (20, 60, 80 and 20%), (-48.9, -43.5, -65 and --41.7 %), (47.1, 14.5, 55.8 and 63.1 %), (17.9, -10.3, 21.3 and 26.7 %) and (237.7, 302.6, 228.6 and 263.6 %) percent increase or decrease than control (26.25, 5, 2.23, 334, 2.41 and 0.77) respectively. The tested molluscicide at rates of 0.05, 0.1, 0.2 and 0.3 gm I m2 induced 58, 72, 79 and 84 % reduction in snails population density respectively under field conditions. | ||||
